David Pastore has gotten pretty good at blocking out potential distractions during the final round of a tournament.

He doesn’t peek at leaderboards, ask his caddie where everyone else is, or try to grab inside info from the volunteers around the golf course. The 22-year-old Pastore likes to play in a bubble until the end of the round.

But, being in the penultimate group during the final 18 holes at the Ike Championship Tuesday, Pastore began to notice something on the 17th hole. He looked back at the final pairing and didn’t see any spectators following along. They had all joined him.

"I figured something was up," Pastore said with a smile.

Yeah, something was up all right: It was the Greenwich, Conn., native up at the top of the scoreboard, all alone, cruising to a four-shot victory at the MGA’s Ike Championship at Montclair Golf Club in West Orange.

During the 36-hole final round Tuesday, Pastore put himself in striking position after the morning round, posting a 1-under 69. But once he went out to the Third and Fourth Nines in the afternoon, he began to run away from the field.

Pastore — who plays out of public courses in the Greenwich area — fired a 3-under 67 over the final 18 holes, the lowest score of the round.

"I started on the (Fourth Nine on Monday) and I was 2-under quickly," Pastore said. "And I had made a bunch of pars where I was just missing short birdie putts. I felt like I could birdie almost every hole on the back. I ended up shooting 2-over, which I was a little disappointed with, but I knew (a low score) was out here. I felt like I got my bad round out of the way."

Fortunately for him, everyone chasing Pastore seemed to have their bad round during the afternoon 18 holes.

Pastore’s 2-under final score was four shots better than New York City’s Sam Bernstein (Century C.C.) and five shots clear of three golfers, including Bridgewater’s Brian Komline (Black Oak G.C.).

Komline had mounted a charge early in the morning round, making the turn at 4-under, but dropped six strokes on the back to finish with a 3-over 73. An afternoon 1-under 69 pushed him to the top of the leaderboard, but not enough to catch Pastore.

"I didn’t know anything until the 10th tee (in the afternoon), when my brother said that David shot 3-under on the front nine," Bernstein said. "At that point, I knew I was three back. I didn’t really change anything. I knew this back side you could make a bunch of birdies and my whole thing this week has been staying patient."

Still, it wasn’t enough to catch Pastore.

The recently graduated member of the Virginia golf team said he plans to turn pro by the end of the summer. Winning the 59th Ike Championship — the met area’s premier amateur tournament — felt like a proper send-off to his amateur career. "I won a college tournament this spring, which was definitely important to me," Pastore said. "But to win this tournament, against these players, in the MGA area — this is definitely up there."
